TECH77448 does say that you need both the IP address and Name. I spoke with a backline tech on why that would be in there and was told its most likley so a network admin would not have to deal with clearing the host cache.

You are correct though, clean host cache on all media servers an you should be fine.

I have personally migrated a master from Solaris to Linux with new IP on new Linux master.

No issues.

As long as you are mindful of possible hosts entries on media servers and clients that need to be updated, there is no configuration database inside NBU where IP address is recorded.
Host cache is the only place where NBU 'hangs on' to IP address for an hour.
In all honesty - a change like this hardly ever takes less than an hour (during which all processes on media servers should in any case be stopped)! Which makes host cache almost a none-issue....

All that remains then is REQUIRED_INTERFACE or PREFERRED_NETWORK...

Good luck! Let us know how it goes!
